Animal Molecular Breeding 2024, Vol.14, No.2, 154-164 http://animalscipublisher.com/index.php/amb 162 trimmed ham weight and longissimus dorsi muscle area suggest that these traits can be effectively improved through both traditional and genomic selection methods. Furthermore, the genetic correlations between performance traits and meat quality traits indicate that it is possible to select for increased growth rates without adversely affecting meat quality, thus optimizing both production efficiency and product quality. While significant progress has been made in understanding the genetic basis of carcass traits in pigs, several areas warrant further research. Future studies should focus on fine-mapping the identified QTL regions to pinpoint the exact genes and causal variants responsible for the observed phenotypic variations. Additionally, integrating multi-omics approaches, such as transcriptomics and proteomics, could provide deeper insights into the molecular mechanisms underlying these traits. There is also a need for more extensive validation of identified markers across diverse pig populations to ensure their broad applicability in different breeding contexts. Finally, exploring the potential of gene editing technologies, such as CRISPR/Cas9, could open new avenues for directly modifying key genetic loci to achieve desired carcass traits more efficiently. By addressing these areas, future research can further enhance the precision and effectiveness of genetic improvement programs in pig breeding.
